Network neighbors cannot access

Network neighbors cannot access

XP cannot access shared folders?
XP cannot share access ??

For example, "// 192.168.0.80 cannot be accessed. You may not have the permission to use the network. Contact the administrator of this server to check whether you have the permission to access the server. Logon Failed: the type of Logon Request that is not granted to the user on this computer ." Which one can help me solve this problem ????

Method 1: remove the Guest account Restriction

Click Start> Run. In the run dialog box, enter gpedit. MSC, open the Group Policy Editor, select Computer Configuration> Windows Settings> Security Settings> Local Policy> User Rights Assignment, and double-click the Deny access to this computer from the network policy, delete the "guest" account. In this way, other users can use the Guest account to access computers using Windows XP through the network.

Method 2: Change the Network Access Mode

Open the Group Policy Editor, select "Computer Configuration> Windows Settings> Security Settings> Local Policies> Security Options", and double-click the "Network Access: sharing and security modes of Local Accounts" policy, change "guest-Local User-initiated identity verification" to "classic: Local User Authentication" by default ".

When other users access a computer that uses Windows XP over the network, you can log on with your own "Identity" (provided that this account is already in Windows XP and the password is correct ).

After this policy is changed, the file sharing method also changes. After the "classic: local user authenticates with his/her own identity" method is enabled, we can limit the number of users simultaneously accessing shared files and set different access permissions for different users.

However, we may encounter another problem. When the user's password is blank, the access will still be rejected. In the past, there was an "Account: A local account with a blank password can only log on to the console" policy in the "Security Options". This policy is enabled by default. According to the deny priority principle in the Windows XP security policy, if the password is null, users cannot access Windows XP computers over the network. We only need to disable this policy to solve the problem.

 

Basic conditions for mutual access between Windows Network neighbors:

1) the computers on both sides are enabled, and network sharing resources are configured;

2) both computers have added the Microsoft network file and print sharing service;

3) both parties have correctly set the IP address in the network and must be in the same network segment;

4) both computers have disabled the firewall, or the firewall policy does not block access from network peers.

Windows 98/2000/XP/2003 access to XP

First, the question about why guest cannot be accessed:

1. By default, XP disables the Guest account

2. By default, XP's Local Security Policy prohibits Guest users from accessing the network.

3. By default, in XP's Local Security Policy-> Security Options, "account: users with empty passwords can only log on to the console" is enabled, that is, any account with a blank password cannot access from the network and can only log on locally. By default, guest has a blank password ......

Therefore, if you need to use a guest user to access XP, You need to perform the preceding three settings: enable Guest, modify the security policy to allow guest to access from the network, disable the security policy in 3, or add a password to guest.

Sometimes you may encounter another situation: when accessing XP, the username in the Login Dialog Box is gray, always a guest user, and cannot enter another user account.

The reason is that this security policy is at odds (Administrative Tools> Local Security Policies> Security Options> "Network Access: sharing and security modes of Local Accounts "). By default, the XP Access Method is "only guests", so you can access it, of course, it is fixed that guest cannot enter other user accounts.

Therefore, the simplest way to Access XP is: you do not need to enable Guest, just change the security policy above to "classic. Other systems can Access XP and enter their own account information.

For access to 2003, guest is disabled by default in 2003, but there is no such annoying XP Guest sharing by default, so you can directly enter the user name and password for access.

A small office LAN is a WINXP system that can be accessed over the Internet and can also see the other computer, but cannot see the computer shared by the other side, prompting that the network path is incorrect, or if you do not have the permission to use the network, this means that I am not quite clear !! The Guest account is also enabled! The firewall of WINXP is also disabled, and the IP address is OK !! I hope you can analyze it !! Thank you very much!

Cause: security policy restrictions exist in Win2000/XP.

Sometimes, Win2000/XP is "smart". Although we have enabled the Guest account, we still cannot access Win2000/XP from Win98, for example, if you use a firewall vulnerability like rising, it will modify the policy of "rejecting access to this computer from the network" and modify the policy as follows:

Start-> Run-> gpedit. MSC-> Computer Configuration-> Windows Settings-> local policy-> User Privilege allocation-> Delete the Guest user in "Deny Access From the network to this computer.

Mutual access between Win2000/XP and Win98

If both computers use the Win2000/XP operating system, it is very easy to set up a LAN. After the hardware connection is complete, under normal circumstances, you can immediately see the other party in "Network neighbors. However, if a computer in the LAN uses Win98, this may not be the case. We often find that although the ping command can pass, mutual access still cannot be achieved in "Network neighbors, what should I do now?

Countermeasure 1: enable Guest users in Win2000/XP. After the Win2000/XP system is installed, two user accounts are created by default, namely administrator and guest ), all users who have not been assigned an account on the local computer will use the Guest account by default. This account has no password. However, this guest account is not enabled by default. You can find the "guest" account in "control panel management tools Computer Management local users and group users, right-click the "guest properties" dialog box and remove the check mark on the "Account Disabled" check box. After exiting, you can access Win2000/XP from Win98.

In fact, after the Guest account is enabled, the biggest benefit is that you do not need to enter the user name and password when accessing Win2000/XP from Win98. This method is more suitable for LAN with uncertain user and high access volume, but it is not applicable to home users.

Countermeasure 2: Check whether there are security policy restrictions in Win2000/XP. Sometimes, Win2000/XP is "smart". Although we have enabled the Guest account, we still cannot access Win2000/XP from Win98, in this case, you need to find "Access this computer from the network" or "Deny access to this computer from the network" from "control panel management tools Local Security Policy local policy user privilege assignment ", check whether there is a guest account or another corresponding account, and then add or delete the account according to different situations.

Countermeasure 3: Disable the firewall on the local connection. A firewall acts as a security system to protect the boundaries between the network and the external world. In WINXP, Microsoft provides users with a built-in Internet Connection Firewall (ICF ), when enabled, You can restrict some insecure information from accessing the internal network. However, if you enable the firewall on a local connection, mutual access between Working Groups will fail, "XXX inaccessible", "you may not have the permission to use network resources", "please contact the administrator of this server to check whether you have the permission to access", "cannot find the network path" and other similar prompts, disable firewall shielding for local connections.

Countermeasure 4: add the netbeui protocol to WINXP. In fact, directly adding the netbeui protocol is sometimes easier to solve the problem of mutual access, and it can solve the problem of enabling the firewall mentioned above. The netbeui protocol is automatically installed during Win98 installation. However, since WINXP no longer provides technical support for the netbeui protocol, it can only be manually added.

Find the WINXP installation CD and go to the "valueadd/MSFT/NET/netbeui" folder, which contains nbf.sys?netbeui.txt and netnbf. INF contains three files. copy the SYS file to the "Windows/system32/drivers" folder on the local machine (here the local machine refers to the computer with WINXP installed), and then copy netnbf. copy the INF file to the local "Windows/INF" folder. The netbeui.txt file is optional. However, the INF folder has a hidden attribute. You must select a display file in the "tool properties" window under WINXP to view the directory.

Countermeasure 5: Enable "file and printer sharing" in Win98 ". This is a very simple but often overlooked problem, that is, although machines with Win2000/XP can find machines with Win98 from "Network neighbors", but they cannot be accessed, this is because "allow other users to access my files" is not enabled in Win98. Enabling this option can solve this problem.

Of course, in addition to the various reasons mentioned above, there are two computers not in the same working group, or the internal IP addresses of the two computers are in conflict, and even include hub faults and line faults.
